Abstract. A long tectonic zone composed of Upper Jurassic to Lower Cretaceous volcanic and sedimentary rocks is recognized along the Asian continent margin from the Mongol-Okhotsk fold and thrust belt on the south to the Chukotka Peninsula on the north. This belt represents the Uda-Murgal arc, which was developed along the convergent margin between Northeast Asia and Northwest Meso-Pacific. Several segments are identified in this arc based upon the volcanic and sedimentary rock assemblages, their respective compositions and basement structures. The southern and central parts of the Uda-Murgal arc were a continental margin belt with heterogeneous basement represented by metamorphic rocks of the Siberian craton, the Verkhoyansk terrigenous complex of Siberian passive margin and the Koni-Taigonos Late Paleozoic to Early Mesozoic island arc with accreted oceanic terranes. At the present day latitude of the Pekulney and Chukotka segments there was an ensimatic island arc with relicts of the South Anyui oceanic basin in a backarc basin. Accretionary prisms of the Uda-Murgal arc and accreted terranes contain fragments of Permian, Triassic to Jurassic and Jurassic to Cretaceous (Tithonian–Valanginian) oceanic crust and Jurassic ensimatic island arcs. Paleomagnetic and faunal data show significant displacement of these oceanic complexes and the terranes of the Taigonos Peninsula were originally parts of the Izanagi oceanic plate.

Submarine landslides are mass movements that transport sediment across the continental shelf to the deep ocean. This phenomenon happens when the shear stress exceeds the frictional resistance of the slope. We analyze a variety of seismic attributes to interpret large submarine slide blocks on the North Slope, Alaska. Results show that the slide blocks appear as mounds with scarps associated with them on the seismic section. The slide blocks vary in size, depending on their distance away from the shelf. The pattern of the slide blocks affects the overlying sedimentation. Geological feature: Submarine slide blocks Seismic appearance: Mound-like steep ramp and scarp characteristics on seismic sections; blocky and irregular features with sharp boundaries on the horizon slices and seismic attributes Features with similar appearance: Mass-transport deposits; Remnant blocks; Reef deposits; Submarine channels; Gullies Formation: Torok Formation Age: Cretaceous Location: North Slope, Alaska Seismic data: Obtained from the Alaska Department of Natural Resources, Division of Oil and Gas, through the tax-credit program ( State of Alaska, 2017 , http://dggs.alaska.gov/gmc/seismic-well-data.php ) Analysis tools: Seismic attributes (such as coherent energy, Sobel-filter similarity, dip magnitude, and dip azimuth) and geobody extraction
